Abstract [en]
We report on the effect of the overall shape of a city on the flow within the street network. We start with a solid round block, aspect ratio, diameter/ height = 6. The block is subdivided into smaller blocks and step by step an increasing number of streets are introduced. In the wind tunnel visualization with helium filled soap bubbled was carried out for obtaining qualitative information about the flow pattern. The pressure distribution on the ground within the street network was recorded in 400 points. CFD predictions provided the overall flow balance; flow entering through the street portals, leaving through the exit street portals and the updraft.
